Those interfaces are for NAT networks, not bridged networks.

The easiest way to set up bridged networking on CentOS 7 is:

    virsh iface-bridge eth0 br0 --no-stp

This command will create a new bridge interface, br0.  The existing interface, eth0, will be added to the bridge, and its current IP configuration will be migrated to the new interface.

(This should work for C8, but I haven't deployed KVM on C8 yet)
